A bicycle rear derailleur (10) includes a base member (12) mountable to a bicycle frame (11). A movable member (16, 116) is movably coupled to the base member (12). A chain guide assembly (26) is rotatably connected to the movable member (16, 116) for rotation about a rotation axis. A biasing element (21) is configured to bias the chain guide assembly (26) for rotation in a first rotational direction with respect to the movable member (16, 116). A damper assembly (38) is operatively disposed between the chain guide assembly (26) and the movable member (16, 116) to apply a damping force to the chain guide assembly (26) when the chain guide assembly (26) rotates in a second rotational direction opposite to the first rotational direction. The damper assembly (38) includes a one-way roller clutch assembly (60) disposed coaxially about the rotational axis and a friction unit (61) extending circumferentially over a circumferential angle coaxially about the rotational axis.
